Can anyone tell me how to get rid of this error? I attached the screen shot. It comes every hour or two in the system log. It doesn't seem to affect any operation, but it is still there. I believe it was caused by an upgrade from a vendor of our medical software since that is when it started, but they claim it had nothing to do with it.

I have looked it up and some ideas of resolving, but this our domain controller as well as our database and I do not want to do anything that might potentially "break" something. I wanted to hear any thoughts from the community before proceeding.

So, please tell me if (1) This is an error to be concerned with and (2) The best and safest way to resolve it.

Sorry I didn't get to this earlier, it will be tomorrow before you get an answer. Anyway.

"This problem occurs because two or more computer accounts have the same service principal name (SPN) registered. Event ID 11 is logged when the Key Distribution Center (KDC) receives a ticket request, and the related SPN exists more than one time when it is checked on the global catalog (GC) for forestwide verification."

Which seems a good explanation, could you have circumstances like this?
